In order to define a crystal structure completely it is suf

On Track to Post-Leyland Recoverye choice of origin are called structure invariants. When it is possible to estimate the phase sum of an invariant, this sum is generally called a phase relationship. Although in principle a phase relationship is always a structure invariant, it is sensible to make the distinction between all invaria

Uwe G. Kersting,Shariman Ismadi Ismailion problem. Crystals, which are usually defined in terms of the long range ordering they display, might appear to be poor samples on which to apply a mathematical model devised to deal with random experiments. It is the realization that the periodically repeating motif could itself be depicted as c
